The lemure appears as a vaguely human shaped mound of flesh around four feet in height, its saggy flesh runs and drips like candle wax as if some foul creator had forgotten to give it a permanent form. It has facial features in only the vaguest sense of the word with a horrible black pit passing for a mouth and dark eyes that hint at the centuries of torture it has had to endure. Its limbs, like the the rest of it, look crudely formed but serves as its only weapons. This humanoid form is only used while moving and when still a lemure looks like a bulging mound of flesh. Some lemure don't even take humanoid form appearing as just a mountain of writhing flesh. Many lemure have the disconcerting habit of altering their faces to look like that of those they are fighting or those that are around it. Lemures normally weigh around two hundred pounds.[1]

Lemures can be found on any of Hell's nine layers though they are most common on Avernus, Hell's first layer. Lemures can also often be found on the Material Plane since as the weakest of the Devils they are also the easiest to summon, bind and control. Lemures form the vital bottom rung of Hell's ecology, when a soul is banished to Hell it first arrives in Avernus, from there it is shepherded to one of the other layers, either the one that is the most suitable punishment for the souls crime or the layer most in need of new slaves. Once the soul reach the appropriate layer it will suffer centuries of torment that drives the soul mad. The soul is eventually striped of any memories it had of its life before Hell, creating a mindless automaton of hate and fear. After centuries of existing in this state the soul becomes a lemure, the building block of all devil-kind. Lemures roam in fleshy hordes destroying and tormenting anything weaker than themselves. More powerful devils can spot the most fiendishly evil of lemure and often chose to promote them to become more powerful types of devils.[1]
